-- Texas commercial and residential property owners now have a dedicated online tool to estimate how much a successful property tax protest could recover. The Ambrose Group has launched the Texas Property Tax Savings Calculator, arriving as 2026 appraisal notices reach mailboxes across the state ahead of the May 15 protest deadline.
Texas carries one of the highest effective property tax burdens in the country, averaging approximately 2.43 percent combined — nearly triple the national average of 0.9 percent. On a commercial property assessed at one million dollars, that translates to $24,300 in annual property taxes. When assessments run 15 percent above true market value, owners absorb an extra $3,645 every year without realizing the overpayment exists.
The calculator closes that information gap. Owners enter their current assessed value, estimated market value, and combined tax rate, and the tool returns projections for year-one, three-year, and five-year savings. The compounding figure matters because a successful protest establishes a lower baseline, reducing every future assessment under Texas's 10 percent annual appraisal cap.
"Most Texas property owners have no idea how much they overpay every year, and that money does not come back unless a protest is filed," said David M. Ambrose, MAI, President of The Ambrose Group. "The calculator gives owners a clear number before they decide whether to move forward. That transparency is what this process has been missing."
The tool particularly benefits commercial property owners, where overassessment dollars run significantly higher than in residential cases. Office buildings, retail centers, industrial properties, and multifamily assets assessed using mass-appraisal methods often show the largest gaps between assessed value and true market value. The firm's Texas property tax consulting services extend the process beyond the calculator for owners ready to file, covering informal protests, Appraisal Review Board representation, arbitration, and litigation.
The Ambrose Group averages an 18 percent reduction in property tax arbitration cases and an additional 15 percent reduction in cases that reach litigation. Those results come from contested proceedings backed by MAI-credentialed appraisers, the income approach methodology, and detailed valuation arguments — not from quick, informal settlements.
Texas law prohibits Appraisal Review Boards from raising assessed values as a result of a protest, meaning no filing has ever increased a property tax bill. Owners who skip the protest window allow the appraisal district's number to remain in effect for the entire tax year. The savings tool quantifies exactly what that inaction costs before the clock runs out on May 15.
